Message:
  • Added new API for sound & sound port to create/open sound device with extended setting, to allow opening sound device with non-PCM format and other settings.
  • Updated symbian_ua/ua.cpp to be able to reopen sound device when audio stream session is using non-PCM data/passthrough codec.
  • Updated stream.c to allow it works with non-PCM data.
  • Added PCMU/A frames processing into non-PCM play/record callbacks in symbian_audio_aps.cpp.
  • Added passthrough codec init/deinitialization in pjsua-lib.
  • Added a new pjmedia_frame_ext helper function, pjmedia_frame_ext_pop_subframes, to pop-out/remove some subframes.
  • Other minor updates/fixes.
